' .Oneof the objects of my'inventionis to provide novelmeans for oscillating a driven "member from arotatingdriving member. 7

A-further object of my invention is to provide novel means by which the stroke of the oscillating, member may be changed in length. i

the oscillating member maybe changed in length, while the driving member is rotating.

-AI further object of myinvention is to' provide va novel mechanical movement of the kind described, which is simple, relatively cheap to make,,which is durable,; not liable to get out of order, and which is capable .of being run at very high speed.

My invention is adaptedto be lused in connection. with :many devicesywhich require to have an oscillating movement imparted to them in effectingtheir functions and where a high rate of. speed of operationisl desira ble, as for instance, the jogging of screens used in the manufacture of flour, or.; for vibrating screens used in screening othermaterials. I My invention may be ap-- plied to jaflvery large number of devices. *jrwhi requirefto. have a vibrating movement imparted to them. 7 e

The novel features ofmy invention are hereinafter fully describedand claimed.
